                                August 6, 1982


EVALUATION OF THE BAE TURBO—SYSTEMS TURBOCHARGER KIT NO. TO4B M2 FOR EXEMPTION
FROM THE PROHIBITIONS IN VEKICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION
2222, TITLE 13, CALIFORNIA ADMINISTRATIVE CODE.


I.    INTRODUCTION
      BAE Turbo—Systems, of 3032 Kashiwa Street, Torrance, California 90505,

has requested by letter dated July 9, 1982, an update to the existing Air

Resources Board‘s Executive Order (E.0.) No. D—97—5.
      The applicant requested that the exemption from the prohibitions of the

Vehicle Code {V.C.) Section 27156 for their add—on turbocharger kit

No. TO4B M2 be updated to include the 1983 model—year Airstream motorhomes

which are powered by a 1982 California certified Isuzu Motors Limited six—

cylinder (L6) heavy—duty diesel engine and is equipped with automatic

transmissfon.

II.   TURBOCHARGER KIT DESCRIPTION

      The purpose of turbocharging an engine is to increase the volumetric

efficiency of an engine by forcing more air into an engine than it would take

in under naturally aspirated conditions.

      The major components of the BAE Turbo—Systems turbocharger kit are a

0.96 A/R ratio AfResearch turbocharger model No. TOAB MZ2, an exhaust manifold

to turbocharger adaptor, and an intake pipe.    The components are packaged with
installation hardware to complete the kit.


       The exhaust manifold to turbocharger adaptor is installed on the OEM

exhaust manifold Tocated on the driver‘s side of the engine.     The turbine

inlet of the turbocharger mounts directly to the adaptor.     The turbine, driven
by exhaust gases, is linked to the compressor by a solid shaft.     Compressed

incoming air is routed to the intake manifold through the BAE Turbo—Systems

intake pipe mounted transversely over the engine.

       Maximum positive manifold pressure is limited to 13 psig by the size of
{and exhaust flow through) the turbine housing.     No wastegate or other active

boost Timiting device is used.

       The cooling of the turbocharger is achieved by direct fan air from the

engine and lubricating oi1 passing through the unit.     The oil is piped from
the filtered main ofl galley to the turbocharger bearing housing.     Oil from

the turbocharger is returned to the oi1 pan.

       No modifications to the OEM tune—up specifications are required when the

turbocharger kit is installed.
III.   TURBOCHARGER KIT EVALUATION
       The detailed description of the Air Resources Board‘s evaluation of the

kit is included in the ARB Staff Report titled "Evaluation of the BAE

Turbocharger Kit No. TO4B M2 for Compliance with the Requirements of Section
27156 of the Vehicle Code," dated June 5, 1981.

IV.    DISCUSSION

       E.0. No. D—97—5 was granted for 1981 and 1982 mode] years Airstream

motorhomes powered by a 1981 California certified Isuzu Motors Limited six—

cylinder (L6) heavy—duty diesel engine and equipped with automatic

transmissfon.


      The applicant is now making their turbocharger kit No. TO4B M2, using
the same 0.96 A/R ratio AiResearch turbocharger, for the 1983 model—year

Airstream motorhomes powered by a 1982 California certified Isuzu Motors

Limited six—cylinder (L6) heavy—duty diesel engine and equipped with automatic

transmission.   The applicant, therefore, is requesting that the exemption for

this turbocharger kit be updated to include these 1983 model—year motorhomes

as well.

      In response to the request, the staff compared the engine design of both

model year (1881 and 1982) Isuzu engine designs.    In particular, the effects
the turbocharger kit might have on the vehicle‘s emissions were evaluated.

Since the 1982 model—year California certified Isuzu heavy—duty diesel engine

(used for the 1983 model—year motorhomes) are carry—over (identical engine

design) from the 1981 modeT—year California certified Isuzu engines used for
the 1982 model—year motorhomes), the staff is of the opinion that the

turbocharger kit will have the same degree of performance/emissions impact on

the motorhomes for whch an update is requested.    Since the test data on a 1981
model—year Isuzu engine showed that the exhaust emissions were not adversely

affected when the turbocharger kit was installed, the staff is of the opinion

that the kit will have no adverse effect on the motorhomes for which an update

is requested.


IV.   CONCLUSION AND RECOMMENDATION

      Based on the above, the staff concludes that the BAE Turbo—Systems

add—on turbocharger kit No. TO4B M2, using an AiResearch turbocharger with an
A/R ratio of 0.96, will not adversely affect the exhaust emissions from 1981

through 1983 model year Airstream motorhomes which are powered by a 1981 or

1982 California certified Isuzu Motors Limited six—cylinder (L6) heavy—duty

diesel engine and is equipped with automatic transmission.   The staff

recommends that Executive Order No. D—97—15 be adopted.
